Biologic Models Creates Intricate, Full-Color Protein Models Using the Mimaki 3DUJ-553 Printer

31 July 2021: Biologic Models, US-based 3D-printed protein model and medical animation provider, is using Mimaki’s 3D printing technology to produce intricate molecular visualization models, bringing protein into the tangible world in incredible detail. With Canadian-based Mimaki customer, Objex Unlimited, the two have successfully embarked on multiple projects for clients in education, research, and art using Mimaki’s full color 3D-printer, the 3DUJ-553. Most recently, Biologic Models and Objex Unlimited have produced models of coronavirus (SARS-CoV-2) to help with the rapid development of countermeasures to address the ongoing outbreak.

Biologic Models has carved out a niche in creating precise 3D models of proteins for research facilities and collectors using clinical research and x-ray crystallography protein data. Initially working in powder-based 3D printing, the company found that printing with a photopolymer-based 3D materials was a more suitable option. Notably this process offered durability, detail, and quick turnarounds, alongside a color gamut 10x that of what is available with powder-based 3D printing. Another draw is how these prints, unlike sandstone, can be easily cleaned with a wet cloth, a necessary attribute in a post-COVID world for Biologic Model customers when displaying such items in exhibits.

“What drew me to Mimaki’s technology was its ability to simultaneously mix clear and color in order to achieve different levels of transparency, and more easily display the internal changes within a protein,” Casey Steffen, Director of Operations, Biologic Models comments. “With our upcoming coronavirus models, we’re tracking individual mutations on a ribbon model of the Spike Protein’s Receptor Binding Domain and assigning each new mutation a unique color. Viewers can learn about how the structure of the virus changes observing both the accumulation of colored residues and changes to the transparent intermolecular bonds.”

Using the 3DUJ-553’s 10-million color capability, Biologic Models’ protein replicas are distinctly colored to make biomedical research clearer and more identifiable to the viewer. 3D printing a tiny protein could include 10,000 or more individual atoms. This requires a level of detail that is easily achievable with the accuracy delivered with Mimaki’s 3D printing technology. Thanks to its multi-colored printing accuracy, Biologic Models bridge the gap between physical and digital, including QR codes that lead to dedicated webpages that are readable at even the smallest 3D printed sizes. “Mimaki 3D prints facilitate both a physical and digital learning experience that was often unachievable because of the limitations of powder-based printing,” Steffen comments. “In fact, a new series of ‘Mechanism-of-Action’ protein models is set to begin releasing later this summer. This series of 3D printed models integrates AR experiences that allow viewers to digitally explore the protein data used to create the 3D printed protein model.”
